On the varistream do you have to calibrate it every time before you use it or do you just need to do it on the first job of the day,it says that you need to turn it up to max and leave it for 10secs before the pump comes on,but do you need to do this before every job.It also has an inline 10amp fuse but with the eco flo that i have it has a 15amp fuse inline already for that,can it be left in or do you need to replace that particular wire so that theres no fuse only the 10amp one on the varistream.Many thanks in advance.
You may be lucky with your set up with no need to calibrate the varistream, I was until I changed my pump, then I had to re-calibrated the varistream, once this is done, there is no need to touch the calibration switch again unless you change something on your system.
The only other dial is the flow rate dial, and this you adjust to what ever flow rate you want, mine stays on the same setting all the time, unless I have a first clean, then I just turn it up a little, this same dial is also the on/off switch.
